This isn't the normal pattern we use in the kernel.

Usually, we say what is being *DONE* at the label, almost like we are
calling a function.  Here's a random example from one of the most
prolific users of gotos in arch/x86:

        ret = kernfs_get_tree(fc);
        if (ret < 0)
                goto out_psl;
...
out_psl:
        rdt_pseudo_lock_release();

See?  The "psl" is doing a "pseudo lock release".

I don't particularly like the labels as-is, but this patch makes them
less clear, IMNHO.  Let's just drop this patch for now, please.
